ACK!! Intake or Chip?!

·Go the CAI first, then save a few bucks up and do the exhaust and the chip together. You will feel the difference between the mods.

Since I haven't performed either mods on the Nitro, take it for what its worth.....
I'd go with the chip first. It has a better track record when it comes to providing empirically proven benefits, whereas the CAI (at least with the stock hood / engine compartment) has a tendancy to produce smaller (if any) proven gains. For a quick fix I'd suggest getting a better-flowing filter for the stock airbox in the interim.

·Aaron, I'm not sure I understand your reasoning?
My thoughts would be more towards flow dynamics and if you are doing changes to the "tune" via the chip, I beleive it would be wasteful without better flow (CAI & Exhaust).
I know zip about the Stage 1, but with the Stage 2 and no Flow improvements, I think it improvements would be minimal.
Is anyone running a Stage 2 with no other engine or exhaust mods? I would like to hear about it?
Hey RT -
I'm in complete agreement with you - the improvements will most certainly be minimal. However, my point of view:
And on that note, I'm off to lunch.

I'm in complete agreement with you - the improvements will most certainly be minimal. However, my point of view:
- A CAI in the stock engine (no ram air modification to the exterior, no fancy shielding to further reduce engine compartment heat for the air channel) has been proven to provide negligible gains. The biggest gain from the CAI is the flow, not the colder, more dense air. This can be closely mirrored by simply dropping in a high-flow filter. The stock airbox in these newer cars are not nearly as restrictive as old ones. Granted, I'm taking this from the lxforums post so that may be a dangerous assumption. Nobody has run a (relatively) controlled test for CAI in the Nitro that I know of.
- A Jet Chip (both stages) perform best when the combustion system is optimized, to be sure. However, I'd rather see less than optimized gains with a chip and a stock exhaust than negligible gains with a mod that costs the same amount. There's still no harm to the engine when the chip is installed prior to the other components, so you aren't hurting anything.
And on that note, I'm off to lunch.

Go for the CAI first. Rule of thumb-- unblock the intake and exhaust of an engine first.
Besides a nice shiny CAI will do wonders for your underhood look.
The Jet Chip produces most gain by advancing the ignition. This will give some power gain without any other changes, but the intake pipe is painfully restrictive in the Nitro and that really needs to go.
I Installed the Jet 2 chip and the CAI together and it was noticeable but things really came together when I added headers and a free flowing muffler.

·Ken, Wise Men think alike.........
Aaron, I too am a 2 year LX Forum Member (Walt SRT8) and quite honestly, I am not sure "one would need to do Dyno Pulls or CMR a vehicle to notice the difference with a CAI alone". I know I could feel the different in "Peep" with that mod alone on my 6.1L (back 2 years ago).
I hope to report back about the Nitro Experience (I just ordered the AEM CAI) after I receive it, and throw it on.
I am with Ken on the restrictions in these DCX air boxes (pitch em').
On another Note: Now, once I research how to adapt a BT Oil Catch Can to the Nitro..........Everyone will want that mod. (Heidi is sending me out one to help with fitment issues, details also pending):smileup::smileup::smileup:
Good points by Aaron, and Ken thanks for elabortaring more. I feel at this juncture, best we can do without a "Tuna" is go: CAI, Exhaust, Chip. And it looks as though that was your direction as well.

Do a search on "air intakes Demystified" for detailed pictures and a dyno sheet on the 3.7 L with a K&N. The intake and baffle is VERY restrictive on the 3.7.
That being said, In my post above, I mention that you can make your own CAI out of sewer pipe and rubber hose. All of these CAI's are overpriced--- I admit I bought one this time-- only to treat myself to the look under the hood.

·Too funny Ken..................
:smileup:
(Really, I think I'll stick to the AEM.....):i_rolleyes:
:smileup:
That's it, I'm getting out a 4" holesaw, drilling the top of the hood, jammin some good ol' sewer pipe thru that there hole and attachin' me one of those bigole' air thingeys, and "I will be the first to have done the CAI snorkel hood mod".:Na_Na_Na_Na:
(Really, I think I'll stick to the AEM.....):i_rolleyes:
I will give you a dollar to do that. One whole dollar. And I'm not talking about some old junky one, but a crisp brand new dollar bill. :chuckle:
Looks like Ken comes along again to save the day with some nice hard data. I previously never noticed the dyno data from that post. I tried to toss my staggering 1 rep point over your way, but I was unable.
XXXRT - I had never really heard of a catch can until you mentioned it. After a little googling... wow. Talk about removing some unnecessary contaminants. You'll definitely want to post up a how-to when you do that mod.

·Nah..........Im a puttin on that there reflecr tape like a ol' striped christmas candy cane...........Thata ways they can see me when I'm a forge'in them gator filled waterin holes...........
I recon' when I'm finished with the enstal, I could get me some on them there :rep:.....cause I know ain't nobody thought much bout it 4 me.
